That Yang Liwei landed on the earth safe from space made all Chinese exited and cheerful删掉that这句话对吗为什么用safe不用safely
问题描述：
That Yang Liwei landed on the earth safe from space made all Chinese exited and cheerful
删掉that这句话对吗
为什么用safe不用safely
答
That引导主语从句不可省略；safe此处补充说明Yang Liwei的状态， 而不是修饰landed,可理解为and he was safe. 类似的句型还有Finally he returned home safe and sound (安然无恙）。
答
that引导的句子That Yang Liwei landed on the earth safe from space
是主语从句，that不能省略。safe是形容词作宾语补足语，补充说明，着地的情况。
答
that句是主语从句,若去掉这句话就有2个主语landed和made,
所以不对.safe from space是修饰杨利伟的,做补语,所以不用safely,因为不是修饰动词的
